CHARLES F. SHUMAKER, 0F SILVER CREEK, NEW YORK.

rename MACHINE.

Application filed September 23, 1920. Serial No. 412,250.

To ll whom it may concern:

Be it known that I, CHARLES F. SHU- MAKER, a citizen of the United States, re-

siding at Silver Creek, in the county of.

Chautauqua and State of New Y ork, have invented a new and useful Im rovement in Jarring Machines, of which t e following is a specification.

This invention relates to machines for shaking or jarring containers or other articles.

The objects of the invention are to provide an efficient and inexpensive machine for shaking or jarring articles; also to provide a machine of this kind which automatically takes the articles to be shaken from a supply or stack of articles and shakes the same, and then discharges them from the machine; also to provide a machine of this kind which subjects the articles to a combined rolling and shaking action; and also to improve the construction of apparatus of this kind in the other respects hereinafter specified.

In the accompanying drawings:

Fig. 1 is a side elevation, partly in section, of a shaking machine embodying the invention.

Fig. 2 is a fragmentary top plan view thereof on an enlarged scale.

Fig. 3 is a transverse sectional view thereof on line 3-3, Fig. 2.

When fruits or vegetables, such as corn have been canned and stored for a period of time, it is found that the water and the natural milk of the corn sometimes sepa-' rate in the cans, thus spoiling. the appearance of the contents of the cans. When these cans are shakenor jarred, the water and milk of the corn again mix and do not a ain separate upon standing. The mac ine shown in the drawings will be hereinafter described as used particularly in connection with shaking cans of corn, but it will be understood that it is not intended to limit the invention to such use, since the machine can,

be used for shaking or jarring other articles.

The machine shown in the accompanying provided with a plurality of step members B, those shown being arranged adjacent to the side members a so as to engage the end portions of the articles or cans C passing through the trough. These step members B as shown, each include an elongated, inclined portion 6 over which the cans are adapted to roll and an edge portion 6' from which the cans are adapted to drop. The step members are preferably also provided with short, inclined portions 6 the object of which will be hereinafter explained. These step members are preferably arranged upon suitable rails or tracks D which are spaced apart and secured on the base member a of the trough, and which in the construction areprovided with metallic strips 03 upon which the cans drop. In the operation of the machine the cans roll over the inclined faces I) and drop over the ed es 6 of the step members onto the track The feeding of the cans through the trough may be eflected in any desired mannor, this being accomplished in the construction shown by means of a conveyer chain or the like E passing over sprocket wheels 8 6 arranged adjacent to the opposite ends of the pp us. The Chain passes lengthwi l through the trough, preferably between the rails or tracks D. In order to impart motion to the chain, either of the sprocket wheels may be rotated in any desired manner. a crank e being secured to the sprocket wheel 6' in the construction illustrated. The conveyor chain is provided with a plurality of flights or fingers F suitably mounted on links of the chain and projecting beyond the same in such a manner as to engage the cans and feed them, preferably one at a time, through the trough A. Any desired means for mounting the flights or fingers on the chain may be employed.

In order to hold the conveyor fli hts or fingers in proper relation to the troug while passing through the same, the conveyor chain is provided at opposite sides ofeach finger or flight with a pair of guide members-or plates G G. In the constructiton shown these guide plates G- G are secured on links arranged respectively in advance and in rear of the link on which the adjacent finger or flight is secured, and the guide plates are provided with side portions or projections which extend into slots, groovesor recessed portions 9, Fig. 3, of the rails or tracks D,

the recessed portions shownbeing formed by rabbeted portions of the rails D, over which the edges of the metal strips 05 extend. Hence the extensions of the guide plates G G rest upon the rail or track D and are held in the recessed portions 9 by means of the metallic strips or bands 61 in such a manner as to hold the conveyor flights in substantially upright positions while passing through the trough. Any other means veyor trough. This end of the chute H is.

provided with a pair of stop members h with which the ends of the cans are adapted to engage and which hold the cans against further movement. Each finger or flight F of the conveyor in passing through the bifurcated end of the chute H engages the foremost can, namely the can resting against the stops h and elevates the same over the stops and carries it through the trough A. After the foremost can has been removed from the chute H, the other cans roll along the chute until the next can engages the stops. The stops h are so positioned with reference to the conveyor chain that the flights or fingers F engage only the can which is in engagement with thestops so that each flight or finger carries only one can through the machine at a time. By means of this construction, a number of cans may be placed on the chute H and the conveyor will remove the cans one at a time from the chute and carry them through the trough of themachine. At the discharge end of the machine, rearwardly and downwardly inclined rails or tracks I are provided from which the cans are discharged by gravity from the machine. If desired, the trough A may be arranged at an angle sothat the cans pass through the same by gravity, thus eliminating the necessity of using a conveyor.

In the operation of the machine the cans are carried by the flights or fingers of the conveyor over the step members B thereof, passing first upon the upwardly inclined portions 1) which causes the cans to roll, thus effecting a mixing of the contents thereof. When the cans pass upon the short, downwardly inclined portions 6 of the step members they will roll in advance of the fingers and thus drop. onto the tracks D while out, of contact with the conveyor flights so that the fingers of the conveyor do not in any way interfere with the free falling of the cans. The apparatus, therefore, subjects the cans to a combined rolling and jarring action, thus ensuring a thorough mixing of the contents of the cans. The apparatus also has the advantage that it requires no attention, the feeding of the cans to the apparatus and the discharge of the cans from the apparatus being accomplished automatically.

I claim as my invention:

1. In a machine for jarring articles, the combination of a pair of guide tracks, a conveyor having upright fingers arranged at intervals thereon, parts on said conveyor which cooperate with said track for holding said fingers in operative positions, and inclined parts on said machine over which said articles are rolled by said fingers and having ends from which said articles drop vertically, each of said fingers carrying only one article at a time through said machine.

2. In a machine for jarring articles, the combination of a conveyor chain, consisting of a pluralityof links, fingers arranged at intervals on said conveyor, each of said fingers being secured to a link, guide tracks for said conveyor, parts secured to links adjacent to said fingers and adapted to engage with said track for holding said fingers in operative positions relatively to said track, and parts on said track over which the articles are passed by said fingers and from which the articles drop. I
